5 Baseline Summary Content¶

Clustering Approach¶

  • Parameter Setting:
    • Embedding Model: all-MiniLM-L6-v2
    • Representation Model: keyBERTInspired, MaximalMarginalRelevance
    • Count Vectorizer
    • CtfIDF
    • UMAP: 150 neighbors, 10 components
    • HDBSCAN: 150 min cluster size
    • Zero-Shot Classification on cluster name
    • Outliers-reduction with Probabilites: 0.075 threshold

Clustering Results¶

  • Clusters Retrieved: 31 in which the most important ones concern:

    1. Socialism
    2. Elections Fraud America
    3. Racism Mexico
    4. Israel War
    5. Elections Europe
    6. Deep State
    7. Trump
    8. Climate Change
    9. White Racism
    10. Coronavirus
    11. Big Tech
    12. Religion

  • Performance Metrics:

    • Silhouette Score: 0.60
    • Davies-Bouldin Score: 0.55
    • Coherence-Score: 0.46
    • Dos Score: 0.2
    • %Outliers: 0.32 (16.8k/52.3k)

Code¶

In order to avoid importing the whole BERTopicUtils.py module, and thus the linked libraries, I have only brought back the function needed to make predictions, it is the same as in the module

In [2]:
def predict_topic(topic_model: BERTopic, sentence: list, num_classes: int = 5, custom_labels: bool = False) -> pd.DataFrame:
    """
    Predict the topic of a sentence using the BERTopic model.
    :param topic_model: The BERTopic model.
    :param sentence: The sentence to predict the topic of.
    :param num_classes: The number of classes to return.
    :param custom_labels: Whether to use custom labels.
    :return: A DataFrame with the predicted topics.
    """
    # Transform the sentence
    _, pr = topic_model.transform(sentence)

    # Get the top indices
    top_indices = np.argsort(pr[0])[::-1][:num_classes]

    # Get the top topics
    if custom_labels:
        top_topics = [(topic_model.get_topic(i), pr[0][i], topic_model.custom_labels_[i+1]) for i in top_indices]
    else:
        top_topics = [(topic_model.get_topic(i), pr[0][i], topic_model.generate_topic_labels()[i+1]) for i in top_indices]
    
    # Create a DataFrame with the results
    df_finals = pd.DataFrame(top_topics, columns=['Topic', 'Probability', 'Label'])

    # Extract the words and sentence
    df_finals['Words'] = df_finals['Topic'].apply(lambda topic: [word for word, _ in topic])

    df_finals['Sentence'] = sentence * len(df_finals)
    
    return df_finals
